SANCTUARY-LAKE.

7 To all whom it may concern! Be it known that I, EDWARD J. KNAPP,

a citizen of the United States, residing at v provide a State of inthecounty of Onondaga and New York, have invented certain new and usefulImprovements in Sanctuary- Ilamps, of which the followingisa speciy a ufication.

- This-invention relates to improvements in sanctuary lamps, and has forits object to novel, simple and convenient fix-.

' ture designed particularly for use in drawing in vvhich lamps of theclass are used. M

A further object'is toprovide a sanctuary slow burning wax is employedinstead of the -various oils which have heretofore served as theilluminant or fuel for such lamps. v I

A further object is to provide novel and simple m ns for conserving thefuel of the lamp so as to prolong the lighting interval as well astending the burning of wax candles.

A further object is to provide novel means f holes 13' from reaching, asby caplllaryatfor the self-adj ustment of ce the p a orearms: the'same.i

I attain these obj forth in the detailed description which follows, andby reference to the accompanying elevation, of one form Figure 1 1s aside Fig. 2.is a top plan of my improved lamp.

diameterthan'the part 9, and has an annuthe bottom of .the candle 10.The" rt 9 isconnected to a' similar concenarranged part or base 11-, bya neck- 'or-column-12. The base 11 is larger in lar recess 11, the saidrecess having perforations 13, at intervals around the neck 12. As thecandle 10 melts away by the heat of the burning wick 10', some of theunconsumed wax may flow over the support 9,

, into the recess 11 of the base 11, and thence drip or gravitatethrough the perforations 13, and is collected in the pan 6.

13' rep'esents an annular flange" depending fromthebottom of theybase 11for, preventing the molten wax flowing through the 'tracti0 f, .the;10ml? betweensaid base and I i arrangement, any res1-' two or moreguide-rods 15, which extend and there is no danger verticallyparallel toeach other to a con- I siderable height above the candle support 9. Whenanew candle is placed invthe upright position on the support 9, betweenthe rods 15, acircularor ringlike weight or follower 16, having holes orways 17 for guide-rods 15, is disposed directly over an concentric tothe top end of the candle 10. The weight 16 is in the form of alheavyring, preferably made out of metal, as considerable weight is requiredto effect a tight seal between the inner sloping surface 16 of the ringand thelupper end or head of the candle to prevent the escape of themolten wax. The opening in the top of the ring 16, is smaller than thediam eter of vthe candle, and the said opening is provided with aninturned-flange 18, which preferably rests upon the tapering or peakedtop-end of the candle. Below the 18 the weight is counterbored forweight. the melting or wasting of the outer circumferential portion ofthe candle is retarded or prevented to such extent'that the weight willride firmly and evenly upon the candle, thereby conserving the fuel andprolonging the light for a period of a week or ten days. withoutrequiring the renewal of the candle. The wax of the candle, as itbecomes melted by the heat of the burning wick, is retained in thecuplike opening 18' between the flange 18 and the top of the weight. Tofurther aid in retaining the melted wax atthe point where the wick isburning. as well as to protect or shield the flame of the wick. fromdrafts, ll insert a transparent chimney 20, (preferably red glass) inthe opening 18' in the top of the follower 16. The lower end of thechimney 20 preferably fits snugly into the opening 18 of the followerand also rests upon the upper side of flange 18. In practice, after thewick has burned for a short time, the melted wax wells up in the chimney20 slightly above the level of the top of the weight 16, as indicated bythe dotted line 21, in Fig. 5. The wick projects slightly above thismelted wax, and burns for a long time, both the wick and the waxcomprising materials that consume slowly. As the candle melts and wastesaway under the heat of the burning wick, the weight 16 and the chimney20 gravitate with the candle, the former being guided by the rods 15,(see dotted lines in Fig. which hold the said parts in true uprightposition, until all of the solid wax of the candle is melted. By thattime the weight, or an internal annular shoulder 22 thereof, comes torest upon the peripheral flange or edge 9" of the support 9. and formstherewith a chamber 23 (see Fig. 7). As a rule, most of the melted waxwhich remains after the weight contacts with the support 9 is confinedin chamber 23. (see Fig. 'i') and the light will continue to burn aslong as any of the wick and waxoil remains. Outside of the weight 16,the candle and its support 9-11-, and the cup 6. is disposed arelatively large transparent cylindrical globe or part 24 (preferablyred glass). the lower end of which snugly fits into the portion 4 of thebase 2, the said end preferably resting upon the ledge 5 of said base.The globe 24 is preferably spaced sufiiciently from all of the partsabove the base to provide a roomy air chamber for supplying therequisite amount of oxygen for the proper burning of the candie afterthe same has melted away to a point below the top of the globe 2i. Thearrows in Fig. 5 indicate the course of the air from the time it entersthe perforations 5' in the ledge 5,.until it finally escapes through theopen top of the said globe. By

referring to Fig. 5, it will be seen that the top portion of the cup 6is smaller in diamexcluding the larger insects, such as beetles andmoths, which are usually attracted by lights of the kind.

To make-up my improved sanctuary lamp ready for operation, the pan 6 isinserted in the base 2 zthe candle support 911 is then disposed in thepan 6; the candle 10 is next placed upon the support 9, and the weight16 is mounted upon the guide-rods and brought into contact with the topoil the candle where it remains. The chimney 20 is next inserted in theopening 18', followed by the insertion of the globe 24: in the base i,and lastly the cage 25 is placed in position. The lamp is then ready tobe lighted. In practice, the candles 10 are made or a slow burning waxand are usually provided in sizes which will burn continuously for 7 to10 days without renewal. Figs. 1 and 5 show the lamp completely awembledready to start a lighting period, and Fig. 7 shows the condition of theworhng parts of the lamp;d1 during the final stages of the said pen Fig.6 illustrates a modification of the sanctuary lamp in which 27represents a hollow base arranged to receive the waste wax cup and thecandle sup rts, and also the lower end of the globe 2d, the said basehaving an annular flange 27'. The

globe 24' is suspended in a collar or ring 28, 1

which is supported some distance above the base 27 by means of rods 29,the latter being suitably secured to the flange 27", and also to thering 28. The upper ends of the rods 29 are formed into book 30 to whichthe lower ends ofichains 31 are attached. The upper ends of the saidchains are attached to an ornamental part 32, which is provided with ahook or loop 33, by which the whole fixture is suspended, as from a e: Ea The working parts of the hanging lamp of Fig. 6 and also the operationthereof, are substantially the same as shown for the standing lamp,illushated by Figs. it to 5 inhorn the Having thus described myinvention, what I claim as new and desire to secure by Letters Patent isI 1.
